Increase the accuracy of the station coordinates

[aschl]

Meteostat currently publishes the coordinates of the stations only with an accuracy of two digits in their lat/lon.
This throws away very important information and creates unnecessary jitter. You can see this in the example below. On the left it shows the location of a station (here airport station in Lisbon) in Meteostat. On the right is shown its location shown by a provider with the full coordinates.

I think the culprit are lines

jasper/cron/export/bulk/gridded/daily.py

Line 74 in 92521f4

ROUND(`stations`.`latitude`, 2) AS `latitude`,

and

jasper/cron/export/bulk/gridded/daily.py

Line 75 in 92521f4

ROUND(`stations`.`longitude`, 2) AS `longitude`,

I would recommend removing these two lines and storing the coordinates in the full accuracy they are provided by the agencies.

Hi @aschl,

May I ask, are you referring to gridded data only (xarray) or did you retrieve the location shown above from the Python lib (e.g. https://dev.meteostat.net/python/stations.html) etc?

Hi @clampr,
Thanks for your swift response. I am referring to the hourly station data as downloaded from the bulk API.
